Application sied Ain-i1 `22,

This invention relates `to machines for. tilling boxes of the tray and shuck type, having reference `to certain improvements in cover or shuck positioning mechanism for use more especially in connection with the machine illustrated in Letters Patent 'ot the United States No. 1,300,752, dated lApril l5, 1919.

The patented machine Vincludes endless conveyer for transporting" complementary trays-and shucks injenldwi'se relation to each other, a" guide-Way for supporting `a ro'yv of shuclrs laterally et the conveyer as it trai'els from one path to'another, said guide- Way having delivery throat portionto receiye the yleading shuck, a :friction element arranged inthe throat portion in close relation to the conveyer, and a plunger head movable in the throat portion' toward and trom the conveyor, which head is operable in one active stroke thereof rto move the leading shock into vengagement with the tric` tion element and in another active stroke to move such shack to the conveyer. Since the leading shuck of the row is positioned in the path ot' the plunger head by the end pressure of the succeeding shucks,V there is liability ot the telescoping and breaking ot' the contiguous edges of the shucks;

. The .object of my invention is to overcome the objection mentioned, and toV that end the invention comprisesvvarious features o construction and combinations ot parts which `will be hereinafter described and claimed.'

In the drawingsj Figure 'l is a side elevation, partlyV insection, of a match-box illin .machine enibodying a preferred form ci? my invention; the shuck positioning `head being shown in its forward or inserting position.

Located at one'iside of the path of vthe upper run; of the carrier, and at a right angle thereto, is a trough 17 Thls. converter passes" adapted to contain a ronT ott'rays which are y ted toward and successivelyv entered in ythe adjacent tray holders of the conveyer. ,At i

al reciprocating head 19 the succeeding. Y shuck receptacles ot theconveyer as the lat! tertravels from its lower kt-o its upper path; therelation of the tray and :shock inserting means being such that complementary trays and shucks Aare inserted in and Sllplorted by the conveyerand the trays are `carried there- `by beneat-ha suitably-[located match supply hopper 20.

1300,762 aforesaid.

The shuck trough 18 is supported adj-a` cent the path of the` blades l5 and in `substantial horizontall alignment with the axis of the wheel 16, the Width of the trough being such that the shocks are guided, .end to end,` with one of the long narrowsides of each shuck supported on a conveyer 211 which extends along the `bottom oi `the Y trough. The `conveyer 2l is `preferably yin` the `:torni or achain which passes about suit*- able sprocket Wheels located adjacenttlie vle-` spective ends of the trough, the Wheel 22 at the delivery end of the trough being lfast on thenmain shaft llfot'the machine so as vto* impel the conveyer 2l, together with the sliuclrs, along the trough. The 'delivery end i of the shack trough "terminates in advance of the depending angular portion 23 of a bar 24 bolted to the underside of the supporting bed 13 and the overhang end portion;` of a depending bar which is affixed to a bracket 24 on the table 13.

trough are upper and lower transverse rolls" 25 which are driven in opposite directions at liighspeed, and are so relatively disposed as to grip tlietorivard endof tlieleading shack and transfer it rapidly to Ltlie shelf against the 'vertical member` 26 oi' tlieflatter,

which member tlius aotsas a stoporabiit, ment for the sliucl. Ingtlie 'present instance thesespeed rolls are tast on spindles journaledi in elongated n bearings ,2S y, projecting thefen'd of the `main iijaiiierjtlie spindles"i` by Ainterniesliing gears 30;

This head is 'forinedon tli e against the side of the shucl: of

The lever has a laterallyfprojecting roll 37 which is` held yieldin gly against the lace of a1 rotating camfBS "by means of a suitablyldisposed springBQT \vli`i `;h A cam is fast on the main sliaftand is of appropriateiorm to eiiect `and'perinit the timed movementsjofftlie len ver.` The upper portion ot thelever Btis'] provided adjacent the head 19 with `a`lateral``-" ly projecting rib. lOyvvhicli, `by actuation ol the leven` is reciprocated across the frontor deliveryl end of the shuck trough.

The timed relation of the mechanism just described is such that as the sliuclrs are ad-4 vanced along the trough 18 the leading sliuck comes in Contact with the opposing rib 4() and tlielatter thus acts asa stopto arrest the movement ot the slincksuntil the head 19" has reached the `limit ot its outward travel as seen in Fig. rl`hereupon, the roiv ofsliucks `is advancedby the conveyer 21 until" the `forward endof the leading sliuclc i is engaged by the rolls 25 `which rolls by vir-' ture of their rapid rotation instantly advance the leading sliuck f until it comesin contactV With tbe' stop 2G,tlius Well separating suoli shuck from the reniainderoftheiroW1 The lever is tlienactuated by the spring 39 to diving the head forward and push the opposing` shuclrninto the conveyei'. wits the head advances,` the rib fill passes in iL'ront` oi, tlv, sliiick trough and halts the row of sliucls until the head has positionedwthe sliucl; in the conveyer12 and has returned to its outer po sition in readiness to engagetlie next sueneeding sliucln and so onli f i Since the surface speed of the constantly driven rolls 25 is in excess of that of the w f t ieed conveyer 21" and the row olsliucks Mounted at the delivery end of theA sliucl; f`
